What if somebody broke into the MIA and put a big mustache on the Rembrandt--isn't that the same thing? "Well, then we would have a felony burglary charge, because somebody entered a building with the intent to commit a crime." What about this "interactive art" phenomenon? Could that sway the mercy of the court?
"We wouldn't charge that criminally. Not unless it damaged the art itself. If you put a rubber nose and glasses on a SnowMN? It may be questionable judgment, or even questionable humor, but nah, that's not a crime."
Every time I watch Nick at Night, I've wanted to slap some sense into Mary Richards. So I have your permission to slap her around on the mall? "As long as you don't knock her off her base and she shatters into 1,000 pieces, go ahead. You can take out your Nick at Night frustrations on a bronze statue, as long as you don't harm her."
